Frame Source Deserializer#

Defined in framework ScanditCaptureCore

Warning

The deserialization API is not yet stable and will still change over the coming releases.

SDCFrameSourceDeserializer#
@interface SDCFrameSourceDeserializer : NSObject

Added in version 6.1.0

A deserializer to construct frame sources from JSON. For most use cases it is enough to use SDCCamera.cameraFromJSONString:error: which internally uses this deserializer. Using the deserializer gives the advantage of being able to listen to the deserialization events as they happen and potentially influence them. Additonally warnings can be read from the deserializer that would otherwise not be available.

- frameSourceFromJSONString:error:#
- (nullable id<SDCFrameSource>)frameSourceFromJSONString:(NSString *)JSONString
                                                   error:(NSError **)error

Added in version 6.1.0

Deserializes a frame source from JSON.

An error is set if the provided JSON does not contain required properties or contains properties of the wrong type.

- updateFrameSource:fromJSONString:error:#
- (nullable id<SDCFrameSource>)updateFrameSource:(id<SDCFrameSource>)frameSource
                                  fromJSONString:(NSString *)JSONString
                                           error:(NSError **)error

Added in version 6.1.0

Takes an existing frame source and updates it by deserializing new or changed properties from JSON. See Updating from JSON for details of how updates are being done.

An error is set if the provided JSON does not contain required properties or contains properties of the wrong type.

- cameraSettingsFromJSONString:error:#
- (nullable SDCCameraSettings *)cameraSettingsFromJSONString:(NSString *)JSONString
                                                       error:(NSError **)error

Added in version 6.1.0

Deserializes camera settings from JSON.

An error is set if the provided JSON does not contain required properties or contains properties of the wrong type.
